Hou-Bi Elementary School



(1)   Rainwater harvesting

Using only simple equipment, our water recycling system collects and purifies rainwater as well as wastewater, and then keeps it in an underground tank, which helps supply our campus irrigation and dissipate heat on the roofs. In addition, a big signboard is erected around the underground tank to demonstrate the detailed steps of our water recycling system and serve as a sign of our down-to-earth approach to eco education.

(2)   Sustainable roofing

We put some buckets and watering kits on the roofs for rainwater recycling, and then we erect two sign boards as a part of our rainwater recycling education. We build up some shade canopies with insulation nets on the building roofs to lower the temperature for students studying on higher floors. Instead of leaving the building roofs as derelict sites, we green these places and provide a new eco-friendly space for our students to better understand the power-saving-carbon-reduction policy.

Sustainable development in local communities:

The following depicts how we bring our sustainable campus project into local communities:

(1)   Sustainability on the campus

Our rainwater harvesting and roof insulation work helps our students understand and, further, appreciate these green efforts, so that they can know the scarcity of water resources in Taiwan and have wiser use of it.

(2)   Global warming issues
